Note: The largest sealing gap value occuring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.

INSTALLATIONK39 is to be assembled into open grooves if rod diameter is less than 40 mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing elements must be oiled with system oil.

NOTESThe permissible sealing gap values of K39 rod seal is given in the below table.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.

INSTALLATIONK61 is pushed onto the piston rod on the clamping flange towards the rod and fixed by fastening. The nut has to be secured. The sliding surface and the cylinder bore should be oiled with oil that must not go into the reaction with the sealing element during the installation process.

NOTESBefore installation the sealing element must be oiled with system oil. Pay attention not to deform the sealing element during installation. Chamfer at the cylinder bore must be proper and free of burrs.

NOTESK705 wipers have to be used with K35 or K704 rod seals to prevent hydrodynamic pressure build up. If that is not possible some precautions have to be taken to prevent hydrodynamic pressure between wiper and seal (see section: Hydraulic Sealing Elements- Sample Designs). At high temperature working conditions FKM energizing O-ring and special mixture PTFE ring are able to be manufactured according to customer’s request.

NOTESK709 type of rod seal can also be used with double wiper lips. For special applications that require high temperatures or resistance to chemicals, rod seal is being manufactured with special mixture of PTFE and FKM material. For heavy duty applications and high pressures the tolerances should change to H8/f8 and please contact our customer service to choose the suitable sealing element. The permissable sealing gap values of K709 rod seal is given in the table below.

Note: The largest sealing gap value occuring on the non-pressurizedside of the seal does have a vital importance for the function of theseal and in this respect it is quite important to use the S value lowerthan the above indicated numbers.

INSTALLATIONIt is very important that the assembly tools must be of softmaterial and have no sharp adges. We recommend using specialassembly tool (see section; Hydraulic Sealing Elements GeneralInstallation) and to have open groove design for dimensions thatare smaller than Ø 40 mm. Before installation the sealing elementsmust be oiled with system oil.

NOTESIt is recommended to use with minimum two piston guide rings in long stroke cylinders, minimum one ring in short stroke and under low radial loads. For special applications that require high temperatures or resistance to chemicals, piston seal can be manufactured with special mixture PTFE and FKM material. The permissable gap valves of K762 piston seal is given in the table below.
